AX_CC_FOR_BUILD: deprecate in favor of AX_PROG_CC_FOR_BUILD
The AX_PROG_CC_FOR_BUILD has seen a lot more updates than
AX_CC_FOR_BUILD, and is generally way more complete. The latter
hardcoded `gcc` as the native compiler fallback and lacks any of
the standard $build- prefix searches.
It also uses non-standard cache vars -- it's using the bfd_cv_xxx
namespace instead of the ax_cv_xxx namespace everything else does.
Otherwise, the macros largely have the same intention: to find a
compiler for the build system, and setup the exe extension. So
deprecate AX_CC_FOR_BUILD and have it redirect automatically.
